Winspace G3 Aero – Legacy Forged, Performance Unleashed

The Winspace G3 Aero is more than a bike. It is the most versatile all-rounder in our lineup and the next chapter in a Canadian cycling legacy. Born from the rugged, unpredictable roads that defined the original Paris to Toronto ride, the G3 builds on the proven foundation of the G2, refining it for the demands of modern riders.

Key Inspiration and Heritage

• Inspired by Michael Barry Sr.’s iconic Paris to Toronto race, the G3 captures the spirit of speed, endurance, and adaptability that defined that journey.
• Its launch was marked by a milestone: Mariposa Bicycles became the first shop in North America to build and test a complete G3, introducing it to riders who demand both performance and heritage.

Key Features:

• All Road Versatility: 45 mm tire clearance lets you run wide gravel tires for adventure or switch to slicks for fast pavement miles.
• Semi Pro Geometry: Balanced handling for confident descending, stable gravel control, and road race agility.
• Aero Efficiency: Refined tube profiles to cut through wind on open roads without sacrificing off-road stability.
• Performance Tuned Carbon: Engineered layup for optimal stiffness to weight, delivering power transfer where you need it and comfort where you want it.
• Integrated Cockpit Options: Sleek cable routing and cockpit compatibility for a clean, modern build.

From Legacy to Launch

The G3 is built for the way Canadians actually ride: pavement to trail, city to countryside, training to racing. It is not just about getting from A to B—it is about owning every kilometre in between.
